Base class for requests that should be executed on a primary copy followed by replica copies. Subclasses can resolve the target shard and provide implementation for primary and replica operations. The action samples cluster state on the receiving node to reroute to node with primary copy and on the primary node to validate request before primary operation followed by sampling state again for resolving nodes with replica copies to perform replication.
